CVE-2026-110958
A vulnerability was found in Wavlink WN530HG4B M30HG4B_V260724. The impacted element is an unknown function of the file api.cgi. The manipulation results in heap-based buffer overflow. It is possible to launch the attack remotely. The exploit has been made public and could be used. Upgrading to version 2026-09-24-841a51c6d5_tclinux.bin is sufficient to resolve this issue. The affected component should be upgraded. The vendor confirms: "We confirm the finding, and it has already been addressed. In the current firmware the api=info&client=app handler no longer builds a shell command: the login script is now invoked through an argument vector (execvp) instead of system(), and the client address is length-limited and null-checked."
